Morning Glory Pool is a vibrant hot spring located in Yellowstone National Park, Wyoming. Known for its stunning, colorful appearance, the pool's hues range from deep blues to bright yellows and oranges, created by thermophilic bacteria thriving in its hot waters. Over the years, the pool's colors have shifted due to human interference, such as objects being thrown into the pool, which has affected the water's temperature and the bacterial colonies.
